By the way, there is a cloning pointer included in the generic_ptr library 
I've been working on recently:

https://svn.boost.org/trac/boost/browser/sandbox/fmhess/boost/generic_ptr

Still no docs, but at least I'm starting to add some tests.  It should also be 
possible (haven't actually tried it yet) to combine the cloning pointer it 
with a shared pointer, like 

generic_ptr::cloning<generic_ptr::shared<T*> > 

to support a combination of deep and shallow copy handles, although you'd have 
to pass the cloning a null deleter to prevent it from double-deleting the 
owned object.
